CT Angiogram

PREP: You should not eat for 4 hours before the exam. You may drink clear liquids up to 2 hours before the exam.

PURPOSE: A CT Angiogram is done to study the vascular system within the body for signs of injuries, tumors, or other disease.

WHAT TO EXPECT: You will be positioned on a special movable table, called a couch, with the area of interest inside the opening of the CT scanner (usually donut shaped). Intravenous contrast is needed. It is injected into a vein in your arm. During the procedure, the couch advances you slowly through the opening in the scanner. You will need to lie very still during the entire test. The technician will ask you to hold your breath at certain times to eliminate motion on the scan.
